The 2014 Greenland-Portugal GEOVIDE bottle data (GO-SHIP A25 and GEOTRACES GA01)

the geovide cruise was carried out coast to coast between portugal and newfoundland via the south tip of greenland, following the ovide line in the eastern part and crossing the labrador sea in the western part. the classical hydrographic rosette was cast 163 times at 78 different geographical positions called stations. while the ctd-o2 probe acquired continuous profiles of the “physical” variables (pressure, temperature, salinity and dissolved oxygen), 22 niskin bottles were closed at different levels during the upcast to provide samples for biogeochemical analysis. after calibration, we find precisions for pressure, temperature, salinity and dissolved oxygen that fit the go-ship international quality requirements. in parallel, but not simultaneously, a trace-metal rosette (tmr) was cast 53 times, also acquiring profiles of physical variables, and equipped with 24 go-flo bottles adapted for the sampling of trace metals. depending on the number of operations, stations were identified as “short” (one single ctd cast), “large” (3 ctd casts), “xlarge” (up to 6) and “super” (up to 11). all along the track of the ship, current magnitude and direction was measured by ship acoustic doppler current profilers, down to 1000m depth.this dataset reports for the classical rosette bottle data for the following essential ocean variables: salinity, dissolved oxygen, total alkalinity, ph, nitrates and silicic acid. it also reports on the measurements of the ctd-o2 probe at the bottle levels: pressure, temperature, salinity and dissolved oxygen.

地理视频巡航自葡萄牙至纽芬兰岛，沿格林兰岛南端沿海岸线往返，东部遵循奥维德航线，西部穿越拉布拉多海。在78个不同地理位置设立站点，共投放经典水文玫瑰式采水器163次。同时，CTD-O2探头连续采集了‘物理’变量（压力、温度、盐度和溶解氧）的剖面数据，在上升过程中，于不同层级关闭了22个Niskin瓶，以提供生物地球化学分析的样本。经过校准，我们发现压力、温度、盐度和溶解氧的精度符合GO-Ship国际质量标准。与此同时，但非同时进行，投放了53次追踪金属玫瑰式采水器（TMR），同样采集了物理变量的剖面数据，并配备了24个适用于追踪金属采样的GO-Flo瓶。根据操作次数，站点被划分为‘短’（单次CTD投放）、‘大’（3次CTD投放）、‘超大’（至多6次）和‘超级’（至多11次）。在整个航线中，通过船舶声学多普勒流速剖面仪测量了流速的大小和方向，直至1000米深度。本数据集报告了以下关键海洋变量的经典玫瑰式瓶数据：盐度、溶解氧、总碱度、pH值、硝酸盐和硅酸。同时，还报告了CTD-O2探头在瓶位处的测量结果：压力、温度、盐度和溶解氧。
